These beneficial bacteria are housed in root nodules formed on legume ... Periodic cytokinin responses in Lotus japonicus rhizobium infection and nodule development, Science (2024).

These bacteria convert or ‘fix’ nitrogen ... molecular mechanisms through which light regulates legume-rhizobia symbiotic root nodule formation and nitrogen fixation,” says Wang.

The key to their success is a type of bacteria called rhizobia, which lives inside nodules, or the little nubs ... So, the girls went to work. A root-hacking plan They attacked their work with ...

Bacteria inside root nodules need oxygen to survive. A pink or red color inside a nodule indicates the oxygen supply is robust and the bacteria are thriving. Disclaimer: AAAS and EurekAlert!

She found GA accumulated in the nodule primordium (the zone in the root cortex where cells start dividing in the early stages of nodule formation) in Medicago infected with rhizobium bacteria.
